Smart TV

A smart TV, also known as a connected TV (CTV or, rarely, CoTV), is a traditional television set with integrated Internet and interactive Web 2.0 features that allow users to stream music and videos, browse the internet, and view photos. Smart TVs are a technological convergence of computers, televisions, and digital media players. Besides the traditional functions of television sets provided through traditional broadcasting media, these devices can provide access to over-the-top media services such as streaming television and internet radio, along with home networking access.

Smart TV is different from Internet TV, IPTV, or streaming television. ''Internet TV'' refers to receiving television content over the Internet instead of traditional systems such as terrestrial, cable, and satellite, regardless of how the Internet is delivered. ''IPTV'' is one of the Internet television technology standards for use by television broadcasters. ''Streaming television'' is a term used for programs created by many producers for showing on Internet TV.

In smart TVs, the operating system is preloaded into the television set's firmware, which provides access to apps and other digital content. In contrast, traditional televisions primarily act as displays and are limited to vendor-specific customization. The software applications, "apps", can be preloaded into the device or updated or installed on demand via an application store or marketplace, in a manner similar to how applications are integrated into modern smartphones.

The technology that enables smart TVs is also incorporated into external devices such as set-top boxes and some Blu-ray players, game consoles, digital media players, hotel television systems, smartphones, and other network-connected interactive devices that utilize television-type display outputs.Intel and Smart TV

Definition

A ''smart TV'' device is either a television set with integrated Internet capabilities or a set-top box for television that offers more advanced computing ability and connectivity than a contemporary basic television set. A smart TV is an information appliance and may be thought of as the computer system of a mobile device integrated with a television set unit. A smart TV runs a complete operating system or mobile operating system that may provide a platform for application developers. Thus, a smart TV often allows the user to install and run more advanced applications or plugins/addons based on its specific platform.

A smart TV platform has a public software development kit (SDK) or native development kit (NDK) with which third-party developers can develop applications for it, and an app store so end-users can install and uninstall apps. The public SDK enables third-party application developers to write applications once and see them run successfully on any device that supports the smart TV platform architecture it was written for, regardless of the hardware manufacturer.

Smart TVs deliver content (such as photos, movies and music) from other computers or network attached storage devices on a network using either a Digital Living Network Alliance (DLNA) / Universal Plug and Play (UPnP) media server or similar service program like Windows Media Player or Network-attached storage (NAS), or via iTunes. It also provides access to Internet-based services including traditional broadcast TV channels, catch-up services, video on demand (VOD), electronic program guide, interactive advertising, personalisation, voting, games, social networking, and other multimedia applications. Smart TV enables access to movies, shows, video games, apps and more. Some of those apps include Netflix, Hulu, Spotify, YouTube, and Amazon.

History

In the early 1980s, "intelligent" television receivers were introduced in Japan. The addition of an LSI chip with memory and a character generator to a television receiver enabled Japanese viewers to receive a mix of programming and information transmitted over spare lines of the broadcast television signal. A patent was filed in 1994 (and extended the following year) for an "intelligent" television system, linked with data processing systems, by means of a digital or analog network. Apart from being linked to data networks, one key point is its ability to automatically download necessary software routines, according to a user's demand, and process their needs.

However, descriptions of the elements of a smart television can be found in public discourse from the beginning of the 1980s, if not earlier, with the introduction of videotex services, particularly teletext information for reception by television sets, leading commentators to consider that televisions and accessories would evolve to encompass a range of related activities. In the words of one commentator: "In the long run, this machine is likely to develop into a multi-purpose receiver, for electronic mail, dealing with the bank, calculations, remote information – and 'Not the nine o'clock news' or 'Casablanca' on video."

In the early 2000s, " Bush Internet TV" television sets and set-top boxes had internet-focused marketing and allowed users to access a web portal made by Virgin Media. This range was a commercial failure.

The mass acceptance of digital television in the mid-late 2000s and early 2010s greatly improved smart TVs. Major TV manufacturers have announced production of smart TVs only for their middle-end to high-end TVs in 2015. Smart TVs became the dominant form of television during the late 2010s. At the beginning of 2016, Nielsen reported that 29 percent of those with incomes over $75,000 a year had a smart TV.

Typical features

Smart TV devices also provide access to user-generated content (either stored on an external hard drive or in cloud storage) and to interactive services and Internet applications, such as YouTube, many using HTTP Live Streaming (also known as HLS) adaptive streaming. Smart TV devices facilitate the curation of traditional content by combining information from the Internet with content from TV providers. Services offer users a means to track and receive reminders about shows or sporting events, as well as the ability to change channels for immediate viewing. Some devices feature additional interactive organic user interface / natural user interface technologies for navigation controls and other human interaction with a smart TV, with such as second screen companion devices, spatial gestures input like with Xbox Kinect, and even for speech recognition for natural language user interface. Smart TV develops new features to satisfy consumers and companies, such as new payment processes. LG and PaymentWall have collaborated to allow consumers to access purchased apps, movies, games, and more using a remote control, laptop, tablet, or smartphone. This is intended for an easier and more convenient way for checkout.
